How do I change STP mode?
How to configure STP?
- STP configuration. Enter Global Configuration mode: switch# configure terminal.
- Root Guard configuration. The Root Guard feature is responsible for verifying if the port on which it was enabled is a designated port.
- STP configuration verification.
What is STP edge port?
A port directly connecting to a user terminal rather than another device or a shared LAN segment can be configured as an edge port. In case the network topology changes, an edge port does not cause a temporary loop. You can enable the port to transit to the forwarding state rapidly by configuring it as an edge port.
How to configure a port as STP ” non edge “?
The workaround right now is to disable the bpdu-block-on-edge feature while the STP converges around the new root bridge. The JunOS STP interface mode docs and this example about Configuring Faster Convergence and Improving Network Stability with RSTP on EX-series Switches would seem to be of interest.
When does a port transition to a non-edge port?
Normally an edge port transitions to a non-edge port when it receives a BPDU. As a security feature we also have bpdu-block-on-edge enabled, which will shut down an edge port that receives BPDUs. This is fine unless you want another switch to take over as root bridge.
Which is the default spanning tree protocol for Ex series switches?
The default spanning-tree protocol for EX Series switches is Rapid Spanning Tree Protocol (RSTP). RSTP provides faster convergence times than the original Spanning Tree Protocol (STP). Because RSTP is configured by default, you only need to use this procedure If another spanning-tree protocol has been configured.
Is the edge port part of the spanning tree?
A port on the switch that is connected to a LAN that has no other bridges attached is an edge port. These edge ports transition directly to the forwarding state. RSTP monitors the port continuously for BPDUs (Bridge Protocol Data Units) in case a bridge is connected. Edge ports do not participate in Spanning Tree.
